TURBINE To all whom it may concern:

Be it known that 1, JOHN A. Gnosnou, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Turbine-Engines, of which the following is a specification.

The invention relates to improvements in rotary or turbine engines; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of the invention is to provide a more efficient and economical rotary or turbine engine than those heretofore known to me.

I present my invention in this application as comprising an exterior casing through which the shaft to be driven passes and which is subdivided by a partition into two communicating chambers in each of which is provided a wheel or rotary member for driving said shaft and a series of stationary blades encompassing a portion of the wheel and adapted to receive the jets of steam discharged therefrom and direct the same against an outer encompassing set of blades carried by the wheel. The wheels or rotary members provided within the chambers of the interior casing are formed or provided with hubs which are keyed upon the shaft to be driven, and these hubs contain passages for the steam, said passages communicating through ports with the discharge or jetpassages within the rotary members, whereby steam is allowed to pass into and from said. members for driving the same.

The invention pertains more particularly to improvements in the turbine engine made the subject of Letters Patent No. 824,113 granted June 26, 1906 to John A. Groshon, and the said invention will be fully understood from the detailed description herei11- after presented, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation, partly broken away and partly in section, of a turbine engine constructed in accordance with and embodying the invention, the sectional portion of Fig. 1 being on the dotted line 11 of Fig. 3; Fig. 2 is an edge view, partly broken away and partly in section, of the same, the sectlonal portlon of Fig. 2 being on the dotted line 22 of Fig. 1; Fig. 3 is a central horizon- .Specification of Letters Patent.

Application filed October 7 Patented May 1 1, 1909.

, 1907. Serial No. 396,166.

1 tal section through the engine on the dotted line 3-3 of Fig. 1, and Fig. 1 is an enlarged side elevation, partly in section, of a portion of the engine.

In the drawings, 10 designates the exterior casing as a whole; 11, the shaft to be driven; 12 a vertical transverse partition subdividing the casing into two chambers, designated 13, 1 1, respectively 15, wheels or rotary members mounted within said chambers, upon said shaft; 16, the hubs of said wheels; 17, a threaded nozzle formed on said casing to receive the inlet-pipe for steam; 18, a corresponding nozzle to receive the outlet-pipe for exhaust steam; 19, a passage cored in one side of said casing for directing the supply-steam to one of said wheels, and 20, a passage cored in the opposite side of said casing for directing the supply-steam to the other of said wheels, both of said passages being in communication with the inlet 17. The chambers 13, 14 communicate with each other through ports 21 so that the exhaust steam from both of said chambers may discharge at the nozzle 18.

The casing 10 comprises two cylindrical sections or shells between which the partition 12 is secured and upon the outer sides of which are formed the hollow hubs 22 through which the shaft 11 is passed and within which is housed the outer portions of the hubs of the wheels 15. Upon the outer ends of the hubs 22 are applied suitable glands or stuffing boxes for the shaft 11.

Each wheel 15 comprises a main bodyportion 23, a hub 16, a dish-plate 25 secured to the outer face of said bodyportion 23 and a ring 26 fastened. to the inner face of said disk 25 adjacent to the outer peripheral edges of the same and comprising side members connected b a series of equally spaced transverse blades 27 of crescent shape. The hub 16 may be formed integrally with the body-portion 23 of each wheel and the disk 25 is secured to said body-portion, while the ring of blades 27 is secured to said disk concentrically with said body-portion but separated by a space therefrom.

Between the periphery of the body-portion 23 and ring of blades 27 of each wheel 15 and secured to the artition 12, is a ring 28 of blades 29, these b .ades being of crescent shape correspondingly with the blades 27 of the ring 26 but being 0 ositely disposed, the concave sides of the l; ades 29 all facing in one direction and the concave sides of the blades 27 all facing in the op )osite direction. The ring 28 of blades 29 snug y fills the space between the periphery of the body-portion 23 of each wheel and the inner edges of the ring 26 of blades 27, as shown in Figs. 3 and 4. The ring 28 being fastened to the partition 12 is stationary and the ring 26 being fastened to the disk 25 of the wheel 15, forms a part of and rotates with the wheel.

Within the inner part of the body-portion 23 of each wheel is formed a steam-chamber 30, and extending therefrom through said body portion are the equally spaced ports 31 and jet nozzles 32, all of the latter being correspondingly arranged tangentially of the wheel and opening at the periphery thereof, while the ports 31 are radially disposed and communicate with and are less in diameter than the nozzles 32, as shown in Fig. 4. The outer ends of the nozzles 32 are squared off and disposed at the advance ends of the recesses 33 formed in the periphery of the body-portion 23 of the wheel. The steam issuing from the nozzles 32 acts to rotate the wheel 15 and discharging against the blades 29 is by them directed against the concave sides of the blades 27, with the result that by its impact against said blades 27 the steam is enabled to exert power at and against the peripheral portion. of the Wheel to further aid in driving the latter. The steam is thus utilized both in the body portion of the wheel and at its periphery to drive the same.

The hubs of the wheels 15 are elongated and pass laterally outwardly through the sides of the casing 10 and into the casinghubs 22, as shown more clearly in Fig. 2, and said hubs are formed with a series of horizontal passages 34 whose inner ends communicate, by means of ports 35, with the chambers 30 of the wheels and whose outer ends are annularly grooved, as at 36, forming ports leading into said passages 34 and communicating with annular chambers 37 formed in the hubs 22 and in communication with the supply-steam passages 19, 20, whereby the steam from the inlet 17 is enabled to pass from the passages 19, 20 into the hubs 22 and thence through the hubpassages 32 and ports 35 into the chambers 30 of the wheels, whence the steam passes through the ports 31 and jet nozzles 32 and escapes from the latter in jets which strike the blades 29 and are by them deflected against the concave sides of the blades 27. The steam escaping from between the blades 27 passes into the peripheral and outer side portions of the chambers 13, 14 and thence exhausts through the outlet 18, the steam from the chamber 14 passing through the ports 21 (Figs. 1 and 2) and entering the chamber 13 at the lower end of the latter, whence it passes to said outlet 18.

The inner ends of the hubs 16 enter and find a bearing within an opening in the center of the partition 12, as shown in Fig. 3, and as may be observed in Fig. 3, the wheels 15 are arranged close to the partition and leave a steam space at their outer sides for exhaust steam.

Between the inner hub-edges of the plates 25 and the adjacent edges of the casing 10 are supplied steel washers 38 to prevent wearing of said plates and casing, and around the outer ends of the hubs 1 6 of the wheel are provided packing rings 39, these rings being at both sides of the annular chambers 37 in the hubs 22, as shown in Figs. 2 and 3, and the inner pair of said rings being connected by bars 40, which maintain the rings in place.

In the operation of the engine, the steam is supplied to the inlet 17 and passes thence through the passages 19, 20, to the annular chambers 37 and thence through the hubpassages 34 to the chambers 30 of the wheels, whence it escapes through the series of ports 31 and nozzles 32 and striking the blades 29 is deflected against the driving-blades 27, the exhaust escaping at the outlet 18. The discharge of the steam through the nozzles 32 will rotate the wheels and drive the shaft, but in order to further utilize the steam the blades 27 are provided so that the jets of. steam after leaving the nozzles 32 may strike them and by impact exert power against the wheels in a direction to rotate them, the object being to utilize the steam to the n. aximum extent in driving thewheels before permitting it to exhaust. The nozzles 32 have their discharge ends at the advance ends of the recesses 33, and said recesses assure the proper escape of the steam from said nozzles and its engagement with the blades 29. The blades 29 alone cooperate with the tangential discharge nozzles in increasing the efficiency of the discharge jets in their action on the wheels, said blades being close to and in position to be struck by said jets.
